Biography

The White Guardian sent the Fourth Doctor and Romana on a quest to find the six segments of the Key to Time, changed into a variety of forms and scattered across time and space. Assembling them, he said, would restore balance and order by freezing all time. He warned them of the Black Guardian, who would try to prevent the assembly of the Key. (DW: The Ribos Operation) With the Black Guardian and four others, he was part of the Six-Fold God known as the Guardians of Time.

The White Guardian and the Black Guardian offered Enlightenment, symbolised by a crystal of unknown powers and great value, as a prize to the winner of a space race undertaken by Eternals. Turlough threw the crystal at the Black Guardian, who vanished in a burst of flames. The White Guardian explained that the Black Guardian would exist as long as he did, until neither was needed any longer. (DW: Enlightenment)

The Black Guardian and White Guardian await the winner of the space race. (DW: Enlightenment)

On another quest to find the Key to Time, the Fifth Doctor and Abby found him in 9th century Sudan, crammed in 'a measly number of dimentions small enough to count on one hand, a human hand' (as he said). He posed as the Legate of the Caliph, the embodiment of law in that era, collecting taxes and punishing tax evaders such as Lord Cassim. He was only in Sudan after he followed The TARDIS there. This was Order's way of finding the fifth segment of the Key to Time. His adversary and he did not trust each other to carry out the Doctor's orders and watched each of other as they worked. When the Doctor left the Sudan, he was stranded there, waiting for the universe to end. (BFA: The Destroyer of Delights)

He remained there for so long he forgot who he was. However Zara found him and took him to Atrios, where he became Professor Lydel, the scientific adviser for President Astra's mission to the Chaos Pool.

Thanks to Amy and the Doctor arriving, he came in contact with the segments of the Key and was rejuvenated. He tried to take the Key from the Doctor when he assembled it, using the Teuthoidian's army, which happened to be on Planet Chaos. He failed and was returned to the Howling Void and his eternal struggle with the Black Guardian by The Grace. BFA: The Chaos Pool)

The White guardian during his meeting of the Seventh Doctor. (DWM: Time & Time Again)

The White Guardian later sent the Seventh Doctor, Ace and Benny on a quest to find the six segments of the Key to Time, scattered across the Doctor's personal timeline when he last disassembled it. (DWM: Time & Time Again)

Behind the scenes

• When Part One of The End of Time aired, it was speculated that The Woman was the White Guardian. She dressed all in white, only appeared to a few people, and tried to help the Doctor without his knowledge. Russell T Davies called attention to her costume and called it a clue on the community^{[statement unclear]}. However, most consider her to be a Time Lady due to her appearances in the second part.
